          算法思路：
          1、当分级大于1时，进行价格分级
          2、取出该类下商品价格的最大值、最小值
          3、根据商品价格的最大值来计算商品价格的分级数量级：
          价格范围(不含最大值)    分级数量级
          0-0.1                   0.001
          0.1-1                   0.01
          1-10                    0.1
          10-100                  1
          100-1000                10
          1000-10000              100
          4、计算价格跨度：
          取整((最大值-最小值) / (价格分级数) / 数量级) * 数量级
          5、根据价格跨度计算价格范围区间
          6、查询数据库

          可能存在问题：
          1、
          由于价格跨度是由最大值、最小值计算出来的
          然后再通过价格跨度来确定显示时的价格范围区间
          所以可能会存在价格分级数量不正确的问题
          该问题没有证明
          2、
          当价格=最大值时，分级会多出来，已被证明存在
